Application filed. February 6, 1924. Serial No.

Our invention relates to andhas for its purpose the provisionot a iiushing device adapted to be manually controlled by the operator of amotor vehicleand which utilizes the suction created in the intake'manifold of an internal combustion engine to supply a sufficient quantity of suitable liquid to the engine of the motor vehicle for effecting the removal oi carbon from the cylinders and valves of the engine. I

It is also a purpose of our invention to provide a flushing device of the alo'ove described character having a measuring tank to which a carbon removing liquid is first supplied from a reservoir tank and sulose quently discharged into the intake manifold of the engine,- the passage of liquid from one tank to the other and its discharge into the manifold being manually controlledthrough the] operation of single valve element.

We will describe only one form of engine flushing device embodying ourinvention and will then point out the novel features thereof in claims.

In the accompanyingdrawings.

Pi ture 1 is view showing in vertical section in one form of engine flushing device embodying our invention; and

Figure 2' is a transverse sectional view taken on the line 2'-2of Figure 1.

Referring specifically to the drawings, in which similar reference characters refer to a similar parts,- our invention in, its present embodiment comprises a metallic base 15 of disk form and having its periphery providedwith' an upstanding annular flange 16 which is riveted or otherwise secured to a cylindrical metallic memherf 1:7 which constitutes the measuring tank ct -the device, The base 1 5'is providedaxially thereof-witha depending'extension 18 provided with a'duct 19 in: communication with an elbow pipe.

20 threadedinto the ,eXte-nson and adapted for coinmunicationwith the intake manifold of an internal combustion engine (not shown) through the medium of a; pipe 21,

detacha'bly associated with the elbow by a connection 22. -E);tending from the upper; side of the base 15 is an annular collar 23" interiorlythreaded to receive a plug 24 havp'osed with respect to a similarly shaped duct 26 formed in the extension 18 and constitutin'g a continuationof the duct 19; Be tween the conical ducts and 2 6 an annular duct 27 is formed in the base which, at times, comnninicates with the interior of the Incas iiring tank 17 through a discharge port 28'.

The plug 24 provides a supporting means for a reservoir tank 29 arranged within the measuring tank 1'? and a frusto conical lower end vprovided with a flange 30 which is welded or otherwise secuied to the plug 24-. The plug is provided at its upper end with recesses 31 in which the p rongs of a spanner wrench are adapted to engage for screwing or unscrewing the plug within the collar 23. y I

The upper ends of the tanks 29 are closed by a cover plate 32 detachably secured to an annulus 33 means of screws 34c. The annulus in turniswelded or otherwise secured to the measuring tank 17 anda packing? ring 35 is preferably interposed between the 'annu'lusand cover plate, as shown. Entend'ingseisny threu h thejev r; late is a rod 3 6Qcarrying at its lower end a valye element V preferably formed of cork and fixedly secured to the rod by means of nuts 37. The upper end of the rod extends exteriorly of the cover plate andhas attached thereto wire 38' or other fiexibl e membjer which is adapted to extend through the dashboard of a motor vehicle or soineother suitablepoint within easy reach or the operator of the vehicle; sprin 39 surrounds the rod and is interposed between the cover plat 32 and a collar 40 fixed to the rod whereby the rod, together with the valve element, is urged downwardly to'theposit'ioii shown in Figure ,1. The .valve eleiiie it is reversely tap red to provide reality two, valvesv 4:1 a'ndj4l2; the valve i1 being adapted toseat iri ,the coiiical duct 25, while the valve 4-2 is adapter to sea] within the sem n duct e6. v Asslidwn iiilTigiireih the cover p lat'e'f 32 i shp royided with: a veiit including a dr fw are,

the intake manifold of an internal combustion engine between the engine and the carburetor. The reservoir tank is adapted to be tilcd with a suitable l quid which, when introduced into the cyl nders of the engine, is adapted to loosen or dissolve the carbon particles adhering to the cylinder head, piston and valves, so that during the operation ol the engine the carbon .ill be removed therefrom; 'With the valve clement V in the position shown in Figure 1, the liquid in the reservoir tank 29 will flow into and till the measuring tank 17 through the duct 25 and the port 28. This measuring tank 17 is designed to receive suii'icient liquid for eli'ectively flushing an engine to remove the carbon therefrom, and the liquid can be discharged from this measuring tank by pulling the rod 36 upwardly against the tension of the spring 39 to cause the valve element to occupy its uppermost position wherein the duct 25 is closed by the valve 41, while the duct 42 is opened or placed into communication with the discharge port 28 so that the liquid in the tank can flow therefrom into the pipe 21 and finally into the intake manifold of the engine. As the liquid enters the intake manifold the suction created by the engine will operate to draw this liquid into the cylinders and thus eii'ect removal of the carbon therefrom.

It will be noted that with the valve element in its uppermost position the discharge of liquid from the reservoir tank into the measuring tank is prevented, and consequently while the liquid is being discharged from the measuring tank no liquid will flow from the reservoir tank into the latter. However, as soon as the valve rod 36 is released the spring 39 functions to move the valve element to its lowermost position, wherein the valve 42 seats within the duct 26 to disconnect the port 28 from the duct. Simultaneously with this movement the valve -11 unseats the duct 25 and thus places the duct in communication with the port 28 so that liquid from the reservoir tank can flow therethrough into the measuring tank, whereupon the latter is again filled and the device ready for a second operation.

From the foregoing operation taken in conjunction with the accompanying drawing, it will be manifest that we have provided a device which can be manipulated by the operator of a motor vehicle to supply one or more charges of carbon removing liquid to the internal combustion engine while the latter is in operation and irrespective of whether the vehicle is under way or at a standstill, whereby those moving parts of the engine where carbon has a tendency to deposit can be kept free and clean. In this manner the accumulation of carbon on the valves and piston rings is prevented and their proper operation at all times insured.

Although we have herein shown and doscribed only one orm of engine flushing device embodying our invention, it to be understood that various changes and modiih cations may be made herein without: depart-- ing from the spirit of the invention and the spirit and scope of the appended claims.
